Abstract |

内容記述 |
To help prevent the spread of SARS−CoV−2, we developed a CO2 monitoring system for university lecture halls and clinical training rooms. This system enables real−time measurement, display, and remote monitoring of CO2 concentrations to determine appropriate timing of ventilation. Through continuous monitoring, we found that indoor CO2 levels can be maintained below 1,000 ppm with minimal ventilation when appropriate countermeasures are in place. In contrast, CO2 concentrations in medical settings, where ventilation was sufficient, did not exceed 1,000 ppm. Additionally, we developed a short−term CO2 prediction model using a Random Forest classifier trained on historical environmental data. This model was able to successfully predict CO2 levels exceeding 1,000 ppm approximately five minutes in advance. These results suggest that data−driven ventilation guidance and automated prediction systems can contribute to effective and sustainable infection control in educational and clinical settings. |
